If Carla is paid an hourly rate of $13.75 and she works 40 hours in a week, we can calculate her weekly gross pay by multiplying her hourly rate by the number of hours she worked. So, her weekly gross pay would be $550.
To calculate her annual income, we need to consider that she works the same hours every week of the year, which includes two weeks of paid vacation. Assuming there are 52 weeks in a year, we can calculate her annual income by multiplying her weekly gross pay by the number of weeks she works in a year (52 - 2 = 50 weeks). So, her annual income would be $550 * 50 = $27,500.
